Question

I’m new to Windows Phone and C#, enjoying the change from Objective-C and Java.

I cant find the way to pass an object from one class to another. I came across some sample code looking on MSDN but I tink that maybe its not applicable for what I need.

    private void meetingList_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        if (meetingList.SelectedIndex != -1)
        {
            Meeting aMeeting = (Meeting)meetingList.SelectedItem;
            this.NavigationService.Navigate(new Uri("/MeetDetails.xaml", UriKind.Relative));
            ApplicationBar.IsVisible = true;
        }
    }

How can I pass my Meeting Object ‘aMeeting’ into my MeetDetails class so that I can display all the details to the user.

I know I can break it down, and pass in all the vars from the ‘aMeeting’ by using something like this:

this.NavigationService.Navigate(new Uri("/MeetDetails.xaml?Meeting=" +
            aMeeting.meetName + "&TheDate=" +
            aMeeting.meetDate, UriKind.Relative));

Is there something I’ve missed? Are there alternative ways you guys would recommend?

Many Thanks,

Answer 1

         var t1 = App.Current as App;
         t1.SSIDToken = stData1SSID;
         t1.CSRFToken = stData1CSRF;

this works real good, just make the members u need in the app.cs file
(here it was :

public string SSIDToken {get; set;}
public string CSRFToken {get; set;}

Then create the top code to create a var to serve as temp buffer.
If you want to get back the values use the same code :

     var t1 = App.Current as App;
     thisisatextbox.Text = t1.SSIDToken;
     thisisalsoatextbox.Text = t1.CSRFToken;

EDIT: After a couple of months of experience, noticed you can add

public static new App Current
{
    get { return Application.Current as App; }
}

In the App.xaml (In the public class App) to be able to call upon App.Current without having to declare it every single time!

Now you can use App.Current.CSRFToken = “” || string CSRFTk = App.Current.CSRFToken;
